Summary

Initializes a new RakeRemoveCommand with explicit parameters.

Syntax

C++/CLI

Python

public RakeRemoveCommandEventArgs( 
   RasterRegion region, 
   int length 
)

public: 
RakeRemoveCommandEventArgs(  
   RasterRegion^ region, 
   int length 
)

__init__(self,region,length) # Overloaded constructor

Parameters

region
LEADTOOLS RasterRegion representing the rake to be removed. It is the programmer's responsibility to dispose of this region when it is no longer needed.

length
Length (in pixels) of the rake base line.

Example

Runs the RakeRemoveCommand on an image.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void LineRemoveCommandEventArgsExample()

   // Load an image 
   RasterCodecs codecs = new RasterCodecs();

   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   LineRemoveCommand command = new LineRemoveCommand(LineRemoveCommandFlags.UseGap | LineRemoveCommandFlags.CallBackRegion, 200, 5, 7, 10, 2, 2, LineRemoveCommandType.Horizontal); 
   command.LineRemove += new EventHandler<LineRemoveCommandEventArgs>(LineRemoveEvent_S4); 
   command.Run(image); 
 
}

}
